A lot of car audio shops sell MLV sheets and also offers installation. Price per sheet varies between brands but each sheet costs around 500 pesos.

will deadening help improve the sound quality assuming all set up (hu, speakers) is stock?

The most apparent use of road deadening sheets is to reduce the amount of road noise. And as noise is typically in the bass region of 200hz, quieting that down gives the user "uy, nice bass!". A very good analogy for this is the seal of earphones. Have you ever tried your typical Apple earbuds versus those that are IEMs? You will notice that everything's "fuller" once you have a good seal on your ears and this draws you to enjoy your music more.

There are actually three types of deadeners: CLDs, MLVs, and CCFs. We're most familiar with MLVs or mass loaded vinyls (usually, shop installers know them as "butyl sheets") because it's the most inexpensive alternative to lead that blocks sound. Aside from blocking the sound via its mass/density it also lowers a panel's resonant frequency. As for the others, CCFs are closed cell foams and is used as a decoupler and CLD sheets on the other hand are used to lessen the vibration around the cabin. Visualize a thin sheet of metal and you hit it... it'll go "tinnggggg", what the CLD does is lessen the decay of the sound so you hear the "ting" for just one second versus three. As a less expensive alternative, you can create your DIY CLD sheets by buying a MLV sheet and cutting it into small pieces then pasting it all over the car.

Will it help? That depends. As different cars adapt differently to deadening. The advantages of deadening a Merc versus a Kia Pride is huge as an example. However, if you are going to deaden, go for the doors first then the flooring as these two contribute the best bang-per-buck in vehicle (floor) and sound (doors usually).

All I can tell you is that two things:
1. I've never seen a professional car audio event contestant without deadeners.
2. I've never seen a noisy car win car audio events. This is the reason why walang nananalo na Isuzu Crosswind

Do you know any shops that offer the product and installation services here in Quezon City, and I assume they also install in speakers, yes?

2 sheets po ba ito per door or isa lang?

Just drop by Banawe Street and you'll literally find tens of them offering speaker installation services. However, deadening is best done by more specialized car audio shops such as Candyshop, Jetcars, Maspro, Dawg Audio, etc.

That would differ from car to car basis. The bigger the car, the more sheets. Also, it depends on how much deadening you would be applying. Remember that your door has the inner panel and the outer panel. A fully deadened door might consume 3-4 sheets per door in fact.
